Title: Improvements in or relating to electric motor control systems
IPC: B60L3/08
Filed: 1945-10-19
Abstract: 603,387. Control of D.C. motors. GENERAL ELECTRIC CO., Ltd., and TURRALL, J. C. Oct. 19, 1945, No. 27522. [Class 38 (iii)] Varying field.-When the speed of a motor reaches or exceeds a given value, switching means operate automatically to increase the field excitation to prevent further speed increase or to reduce it to the given value. A series field diverter may be controlled by a relay which is lifted through operation of the controller when accelerating and is retained by armature current so as to release under excess speed conditions. In the Figure, a trolleybus motor armature 4 and series field winding 5 can be connected to trolleys 1 and 2, through starting resistance 7 and reverser 16, by the line switches 12 and 14 ; the shunt field winding 6 can be connected to the trolleys through resistance 10 by contactor 26. The speedresponsive relay has a divided winding 13 in series with the motor, a lifting winding 34, and contacts 35. The master controller 31 on its first step energizes the line switches 12 and 14, and the under-voltage relay 33. On its second step-if relay 33 closesthe controller energizes the shunt field contactor 26 and the winding 34 which lifts the speed-responsive relay and closes contacts 35. On subsequent steps the controller energizes the starting resistance contactors 18-21. On the eighth step the controller de-energizes the field contactor 26 and winding 34, and if the armature current be sufficient for winding 13 to hold 35 closed, the contactors 22 and 23 can be closed on the next steps, to connect diverter resistances 8 and 9 in parallel with a part of the series field winding and the part 13A of the relay winding; the ampere-turn ratio of the two parts 13A and 13B is the same as that of the two parts of the series field winding. Should the vehicle speed exceed say 30 m.p.h. the reduced armature current will drop the relay 13 and open contacts 35, which can be re-closed only by moving the controller back to re-energize winding 34 ; the diverter contactors 22 and 23 will re-open unless the vehicle be running down hill. To compensate for varying line voltages, the relay may have a winding responsive to line voltage and opposing winding 13. The brake controller 32, electrically interlocked with controller 31, energizes a dynamic braking contactor 39 which deenergizes line switches 12 and 14; the brake controller can also apply air brakes. The reverser 16 can disconnect the armature and series field from the trolleys and connect them to a battery 3 through the battery switch 17.

Title: Preparation of tertiary-aminoalkyl amino-alkoxybenzoates
Filed: 1955-10-04
Abstract: 794,754. Tertiary-aminoalkyl amino-alkoxybenzoates. STERLING DRUG, Inc. Oct. 4, 1955 [Oct. 15, 1954], No. 28235/55. Class, (2) 3. Dialkylaminoalkyl amino - alkoxybenzoates, the alkoxy substituent having 1-6 carbon atoms, the term "dialkylamino" including N- heteromonocyclic radicals of 5 or 6 ring atoms which may be alkyl substituted, and the number of carbon atoms in the alkylene radical connecting the carboxylic oxygen to the dialkylamino radical being 2 to 4, the valence bonds of said alkylene radical being on different carbon atoms, are prepared by esterifying an alkali metal salt of an amino-alkoxybenzoic acid with a dialkylaminoalkyl halide. This process may be combined with the preparation of the amino-alkoxy benzoic acid by hydrolysis, preferably by heating at 50-150 C. in an aqueous alkali medium, of the corresponding alkyl (lower alkanoylamino)-alkoxy benzoate (the alkyl group containing 1-6 carbon atoms), this being prepared by reacting an alkali-metal salt of the corresponding (lower alkanoylamino)-hydroxybenzoic acid with an alkyl ester of a strong acid, e.g: n-propyl bromide, dimethyl sulphate, ethyl benzenesulphonate or n-pentyl paratoluene sulphonate, preferably by heating e.g. at 100-160 C., in presence of an alkali metal carbonate in a non-polar solvent, e.g. methyl isobutyl ketone, toluene, xylene, diethyl ketone or 2-heptanone. The esterification is preferably carried out by heating the reactants in a non- polar solvent, conveniently by first heating the acid with an alkaline base, e.g. an alkali metal carbonate, in the solvent, removing the water as it is formed and then heating the alkalimetal salt with the dialkylaminoalkyl halide, the reaction temperature and non-polar solvents being the same as those used in the dialkylation step. In examples, 4-amino-2-hydroxybenzoic acid is acetylated, the 4-acetylamino-2-hydroxybenzoic acid is dialkylated with n-propyl benzenesulphonate to yield n-propyl 4-acetylamino-2-n-propoxybenzoate, this is hydrolysed to 4 - amino - 2 - n - propoxybenzoic acid and this is esterified with 2-diethylaminoethyl chloride to yield 2-diethylaminoethyl 4-amino- 2 - n - propoxybenzoate, the monohydrochloride of which is described. The preparation of n-butyl 4-acetylamino-2-n-butoxybenzoate from 4 - acetylamino - 2 - hydroxybenzoic acid and n - butyl benzenesulphonate, of ethyl 4- acetylamino - 2 - ethoxy - benzoate from 4- acetylamino - 2 - hydroxybenzoic acid and diethylsulphate, of 4 - amino - 2 - n - butoxybenzoic acid by hydrolysis of the acetylated, butyl ester thereof, and of 2-diethylaminoethyl 4 - amino - 2 - n - butoxybenzoate and its monohydrochloride is also described, and lists of further intermediates and final products are also given.

Filed: 1948-11-02
Abstract: 646,909. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd. (Maatschappij van Berkel's Patent N.V.). Nov. 2, 1948, No. 28400. [Class 28(ii)] The adjusting mechanism of a slice thickness gauge is mounted on the knife axis and so clear of any scraps which fall on the usual mechanism mounted on the base. The slice thickness gauge 6 is supported and adjusted by a sleeve 13 which is axially movable by rotating a hand knob 16 arranged on the axis of the knife 5. When the knob 16 is turned a cam groove therein acts on a pin 14 fixed in the sleeve 13 to move the sleeve axially. The gauge 16 is at the same time also moved parallel to the plane of the knife 5 so as to make the gap between the knife edge and the gauge 6 at least equal to the adjusted thickness of the slice which passes through this gap. This movement is obtained by making the outside periphery of the stem 11 of the knob 16 eccentric to the knife axis so that rotation of the knob moves the surrounding boss of the gauge-carrying bracket 12 radially to or from the knife axis. A pin 19 in a slot in the gauge 6 helps to guide or steady it.
